oLosEr CONNECTION.

Application filed January 12, 1923. Serial No; 612,173.

The present invention relates broadly to drainage connections, and more particularly toconnections of the type especially adapted for usebet-ween closet bowls and soil pipes.

It is essential that-connections of this char-- .acter be both gas and water tight. It is also desirable that :they be of such nature that it will be unnecessary to specifically shape the outlet horn of the closet bowls. This invention provides these desirable characteristics in an easily installed ant comparatively inexpensive fitting.

Inthe accompanying drawings there shown for purposes of illustration only a preferred embodiment of this invention, it being understood that the drawings do not define the limits of this invention and that changes maybe made in the construction disclosed without departing from the spirit of the invention or scope of our broader claims. H

'In the drawings,

Figure 1 is a" vertical 7 through the lower portion of a closet bowl and the upperportion of a soil pipe illustrating our improved connection; 1

Figure 2 is a top plan view of the connecting member;

F igure3 is a vertical sectional view, corresponding to Figure l,"on an enlarged scale, illustrating the parts in position before compression of the packing gasket;

Figure 4 is a view, corresponding to Figure 3, showing the gasket'compressed, and

Figure 5 is a'transversesectional view on the line V-V of Figure 2. i

In carrying out the present invention, there may conveniently be provided a floor flange 2 in the nature of a casting, such as cast iron, of generally annular shape. This casting may have slots 3 for the attachment thereof to the base flange of thecloset bowl as is understood in the art.

Preferably, the flange is shaped a plurality of substantially equi-distantly spaced pocketsw5, which pocketsare adapted to receive the outwardly bent ends 6 of legs 7 extending upwardly from a packing re ceiving seat 8. The packing receiving seat 8, and the legs 7 may be of integral construction and are preferably of a comparatively non-corrodible material such as bronze. It has been found that the ends 6 may be sectional view inner wall of thesoil pipe.

to provide spaced from the tapered inner surface of the floor flange an amount substantially equal to the average thickness of a soil pipe, such as the pipe 10, to which connection is to be made. The base portion 11 of the packing receiving seat has an external diameter which is substantiallyequal to the internal diameter of the soil pipe 10, whereby it may, tightly engage the same when slipped into position within the upper end of the 1136. I

When itis desired to make connection with the soil pipe, a portion of the upper end thereof may be flared outwardly in any desired manner. This flared portion will then easily receive the base portion 11 ofv the packing receiving seat and. the diverging jlegs 7 which support the same. .As the seat continues to slide into position, the upper' edge of thesoil pipe will be forced into the spaces between the legs and'the floor flange whereby it will be securely gripped, and the base portion 11 of the seat '8 will engage I the interior of thesoil pipe. V

In order to permit the seat 8 to be tightly sealed in position withinthe soil pipe, it has a portion of its outer wall cut away to provide a recess 12 between the same and the The seat is then preferably soldered in position by flowing solder into the recess 12, as will be readily apparent to those skilled in the art. :In Figure l, the'seat is shown soldered in'position.

For forming a seal between the lower end of the outlet horn 9 and the connection, the seat 8 is provided with a groove 13 which is preferably of taperedcrosssection decreas-' ing in'width downwardly. This groove is tionof which directly engages the outlet horn. While this gasket may be of any desired construction, it is preferably constructed as disclosed in. theaocompanying application of John C. Cromwell, filed January 12, 1923, Serial No. 612,258.

In Figure 3, the gasket is shown before it is compressed whilein Figures 1 and 2 the gasket is shown as substantially completely compressed. It will be understoou that the packing groove 13 holds the packing in the desired position, and that the compressing force is exerted on the packing in a direction substantially at right angles to the flat lower end of the outlet horn.

At the present time, it is customary to construct closet bowls with both long and short outlet horns. e have disclosed herein a bowl having a long outlet horn. It

i havin an outlet horn a soil aipe. an annular floor flange surrounding the upper end of said pipe, apacking receiving seat extending within said pipe, and means securing said seat to said flange, said means extending upwardly through the annular flange and being spaced therefrom to provide a soil,

pipe receiving recess therebetween, substantially as described. r

2. In a drainage connection, a closet bowl having an outlet'horn, a soil pipe, an annular floor flange surrounding the upper end of said pipe, a packing receiving seat extending within said pipe and having a packing receiving groove therein, and means securing said seat to said flange, said means extending upwardly through the annular flange and being spaced therefrom to provide a soil pipe receiving recess therebetween, substantially as described. I

3. In a drainage connection, a closet bowl having an outlet? horn, a soil pipe, an annular floor flange surrounding the upper end of said pipe, and a packing receiving seat extending within said pipe and having a welded connection with said flange, said seat and welded connection being so disposed with relation to the inner wall of the annular flange as to provide a soil pipe receiving recess therebetween, substantially as described.

4. In a drainage connection, a closet bowl 'havingan outlet horn, a soil pipe, a floor flange surrounding the upper end of said i e a ackin receivin 'seat extendin 7 c 33 b 2 within said pipe, said seat having an external diameter substantially equal to the interior diameter of said pipe and adapted to engage the interior wall thereof, and upwardly and outwardly diverging legs securing said seat to said'flange, substantially as described.

5." In a drainage connection, a closet bowl having an outlet horn, a soil pipe, a floor flange surrounding the upper end of said pipe, and a packing receiving seat carried by said flange'and extending within the pipe. said seat having an external diameter substantially equal to the internal diameter of said pipe and having a portion thereof cut away to provide apa'cking receiving space between the seat and the wall of the pipe, substantially as described. i

6. As an article of manufacture, a closet connection comprising an annular floor flange adapted to surround the upper end-of a soil pipe, a packing receiving seat, and legs extending upwardly from said seat and through the flange in spaced relation to the inner wall thereof, said legs being welded to said flange, substantially as described.

7. Assn article manufacture, a closet connection comprising a floor flange, a packing receiving seat, and legs extending upwardly from said seat and welded to said flange, said legs providing a soil pipe receiving space between the same and one surface of said flange, substantially as .described.

8. As a article'of manufacture, an outlet 'means being spaced from the inner surface of said flange to provide a soil pipe receiving recess therebetween, substantially as dc-' scribed.

10. In a drainage connection, a closet bowl having an outlet horn, a soil pipe having a flaredupper portion, a floor flangesurrounding said outlet horn and said pipe, a gasket receiving seat carried by said flange and exconnection for closet bowls comprising an tending within said pipe, and a gasket on said seat in alinement with said outlet horn, substantially as described. 1

In testimony whereof we have hereunto set our hands.
